The Injection Blow Moulding process is ideal for producing high-precision,
thin-walled, hollow plastic parts, particularly containers for cosmetics,
pharmaceuticals, food packaging, and beverages.

Injection blow moulding process

• Material Feeding: Plastic resin (e.g., PET, HDPE, PP) in pellet or granule form is fed into a hopper.
• Melting & Injection: The material is conveyed by a rotating screw within a heated barrel, melting and mixing  it into a smooth, uniform state.
• Injection item Formation: The molten plastic is then injected under high pressure into an injection mold around a core rod.
• Cooling (Partial): The product cools and solidifies partially while still attached to the core rod.

Blow Moulding (Container Shaping)

• Transfer: The partially cooled preform, still on the core rod, is automatically rotated and transferred to a blow mold station.
• Inflation: Once in the blow mold cavity, compressed air is introduced through the core rod, inflating the soft plastic preform outwards to conform to the shape of the blow mold.
• Cooling : The now-shaped plastic container cools and solidifies completely within the blow mold.

Ejection & Quality Control

• Ejection: Once cooled, the finished product is ejected from the core rod and the mold.
• Trimming (f necessary): If necessary any excess plastic (flash) may be trimmed, as IBM typically produces minimal waste.
• Quality Checks: Products undergo rigorous quality control, including leak tests using pressurized air, to ensure integrity and adherence to specifications.
